The unit we are doing is Measurement and a question I had problems with is: 1c pg.188.
When I first saw this question the only clues they gave you was the diameter is 12756km and you have to find the SA first I approached it by writing out the formula for SA of a sphere then since you need the radius I divided the diameter by 2 the problem I had was multiplying by the fraction so i multiplied by 4 then divided by 3.
New Steps-
- Determine the Formula.
- plug in numbers.
- deal with fraction.
